Learn more about Pressure Transmitters.

Gauge Pressure
Gauge Pressure transmitters compare a pressure relative to atmospheric measure.
Differential Pressure
Differential Pressure (DP) is defined as the difference between two pressures. Differential Pressure Transmitters use a reference point called the low-side pressure and compare it to the high-side pressure. Ports in the instrument are marked high-side and low-side.
Absolute Pressure
Absolute Pressure transmitters compare a pressure relative to Absolute pressure. Absolute pressure is always a positive value.
Diaphragm Seal System
Diaphragm Seal System can be used to measure liquid, gas, or steam flow as well as liquid level, density, and pressure.
Wireless Differential Pressure/Pressure Transmitters
Yokogawa offers a complete line of ISA100 compliant pressure transmitters. The line includes transmitters that can measure differential pressure, absolute pressure, and gauge pressure.
Liquid Level
Accurate level readings are essential to the safe, reliable, profitable operation of your plant. Liquid Level transmitters measure differential pressure to infer the level in a vessel.
Mass Flow (Multivariable)
There are several technologies on the market to measure mass flow. One is the Multi-variable Pressure Transmitter.
Multi-Sensing
A Multi-Sensing transmitter combines transmitters for Differential Pressure, Gauge Pressure, and Temperature into one field instrument.
- EJX910A
- EJX930A
Draft Pressure
Draft Pressure transmitters are a unique type of differential transmitter that is designed to measure small differences in very low static pressure environments.
Low Flow
Using Bernoulli’s equation, Differential Pressure transmitters can be used to infer the flow of fluid through a pipe.
Hygienic Pressure Transmitters
Hygienic Pressure Transmitters are designed to fulfil the requirements of hygienic and pharmaceutical application.

Pressure Transmitter Initiatives

Based on YOKOGAWA “Trusted Green” sustainability guidelines for the product lifecycle, we strive to ensure the sustainable and stable operation of our customers’ plants with our differential pressure transmitters.

Product Lifecycle	Initiatives Related to the Environmental Contribution of Products	Pressure Transmitter Initiatives
Design	Carbon footprint	Pressure transmitters are designed using LCA (Life Cycle Assessment), and their environmental impacts are calculated and reduced compared to previous models. Pressure transmitters are accompanied by product manuals that are being shifted from paper to web publication, contributing to the reduction of environmental impact.
Procurement	Sustainable materials	Pressure transmitters are finished with powder coating as part of ongoing efforts to reduce VOC (volatile organic compound) emissions. Pressure transmitters are built with materials and parts prioritized for low environmental impact, based on the YOKOGAWA Green Procurement Guidelines.
Production	Environmental risk management	Pressure transmitters are designed and managed in compliance with domestic and international environmental regulations (RoHS, REACH, etc.), with hazardous substances thoroughly controlled and environmental impact reduced.
Production	Carbon footprint	Pressure transmitters are manufactured under the NYPS (New Yokogawa Production System), with production volumes leveled and the entire manufacturing process improved, while inventory disposal is minimized. Pressure transmitters are manufactured with continuous efforts to reduce CO₂ emissions (Scope 1 and 2) through factory-level energy‑saving initiatives.
Logistics	Carbon footprint	Pressure transmitters are packaged using materials that are under review, and the amount of plastic used in product packaging is being reduced.
Usage	Longebility	Pressure transmitters are being continuously improved to increase mean time between failures (MTBF). Pressure transmitters are enhanced for long‑term stability, and the frequency of periodic calibration is reduced.
	Repairbility	Pressure transmitters are supported with information on replacement parts, and repairability is being improved. EJX S series pressure transmitters feature a modular design that allows major components —such as the display, terminal block modules, and main modules—to be individually removed and replaced, improving on-site maintainability.*
	Maintainability	To enhance maintainability, pressure transmitters are designed to allow on-site maintenance work —such as loop testing, tag changes, and range adjustment—to be performed without the use of dedicated tools. For efficient maintenance and troubleshooting, pressure transmitters support diagnostics and configuration using a variety of tools, including FieldMate. Throughout the product lifecycle, pressure transmitters are supported by maintenance manuals, calibration certificates, material certificates, and other relevant documentation provided via the member portal site, contributing to improved maintainability. EJX S series pressure transmitters are provided with a graphical display in which the normal process screen and the alarm screen are automatically alternated when a diagnostic condition occurs, ensuring immediate operator awareness and enabling rapid on-site detection of abnormalities and faster recovery.*
End of Use	Lifecycle management	Pressure transmitters are continuously being redesigned to shorten disassembly time. By continuously reviewing packaging methods, the ease of processing packaging materials is being improved. EJX S series pressure transmitters are designed for easy disassembly at the module level without the use of special tools, contributing to improved ease of processing.*
The Entire Lifecycle	Goal setting and management system	Pressure transmitters are designed and managed based on Yokogawa’s Trusted Green guidelines and our own standards.
